Aftermarket tuners are slowly starting to show some love and affection towards the new G11/G12 BMW 7 Series. Take for example this 2016 BMW 750i which went through a tuning clinic at Noelle Motors, a company that knows a thing or two about engine upgrades.

The man behind the company is Karl-Otto Noelle, once the head of engine development for ALPINA, and a guru of turbocharged engines. So it comes as no surprise that this 750i makes 629 horsepower and 605 pound-feet of torque.

The German tuning shops says there are no exterior or interior upgrades included in this program, and it has rather focused on a three-stage upgrade. The first stage – dubbed S1 – is a simple ECU remapping which gives the V8 turbo 590 horsepower and 560 pound-feet of torque, an improvement of 145 horsepower and 80 pound-feet of torque. The standard sprint is now rated at 4.0 seconds compared to 4.7 seconds in the standard model.

Noelle’s S2 upgrade adds a free-flow exhaust downpipe to the remapping of the ECU. This upgrade puts the 750i’s output to an impressive 609 horsepower and 583 pound-feet of torque. The standard sprint to 62 mph time is 3.8 seconds.

The top upgrade – S3 – adds modifications to the turbochargers as well as the installation of larger downpipes and the remapping of the engine’s control unit. With its 629 horsepower, the 750i will now run to 62 mph in 3.6 seconds.

Noelle Motors hasn’t revealed the pricing details of any of the three-stage kits.
